Multiple-instance learning with pairwise instance similarity

Liming YuanJiafeng LiuXianglong Tang — 2014

International Journal of Applied Mathematics and Computer Science

Multiple-Instance Learning (MIL) has attracted much attention of the machine learning community in recent years and many real-world applications have been successfully formulated as MIL problems. Over the past few years, several Instance Selection-based MIL (ISMIL) algorithms have been presented by using the concept of the embedding space. Although they delivered very promising performance, they often require long computation times for instance selection, leading to a low efficiency of the whole...

Abnormal prediction of dense crowd videos by a purpose-driven lattice Boltzmann model

Yiran XuePeng LiuYe TaoXianglong Tang — 2017

International Journal of Applied Mathematics and Computer Science

In the field of intelligent crowd video analysis, the prediction of abnormal events in dense crowds is a well-known and challenging problem. By analysing crowd particle collisions and characteristics of individuals in a crowd to follow the general trend of motion, a purpose-driven lattice Boltzmann model (LBM) is proposed. The collision effect in the proposed method is measured according to the variation in crowd particle numbers in the image nodes; characteristics of the crowd following a general...
